采用烧结-锻造工艺制备了高效率的ε-Zn 4Sb 3块体试样。使用名义化学计量的粉末混合物获得了具有残余ZnSb的近单相Zn 4Sb 3。在烧结锻造试样的热电性能作为温度的函数进行了研究高达600 K，并与其他研究的结果进行了比较。在室温下的运输性能也进行了评价。烧结-锻造法制备的Zn_4Sb_3的热电性能与文献报道的相当。烧结锻造提供了一种潜在的工艺路线，以生产大块Zn 4Sb 3。
Sinter-forging technique was applied to produce high efficiency ε-Zn4Sb3bulk specimens. Near single phase Zn4Sb3with a remnant ZnSb was obtained using nominal stoichiometric powder mixtures. Thermoelectric properties in sinter-forged specimens as a function of temperature were investigated up to 600 K and compared with results of other studies. Transport properties at room temperature were also evaluated. Thermoelectric properties of Zn4Sb3processed by sinter-forging are comparable to the published data. Sinter-forging offers a potential processing route to produce a bulk Zn4Sb3.
